1 Claim.

This invention relates to pivotal hinges and particularly to hinges adaptable to vehicle ventilators.

Though machining practice and techniques have been greatly advanced re'centyears, there still occurs slight variances even in mass production of parts. This is especially true in press steel stamping, since they must be repeatedly handled before final assembly, and may therefore be sprung out of the desired dimension. Thus two adjacent subassemblies may not, in final assembly, coincide perfectly. This is often the, case in assembling automobile doors and ventilators. Many of the ventilators of the pivotal type must be forced to coincide with the rigid door frame. This places a strain on the present day hinges which usually comprise two angular offset pieces riveted together. The strain may merely increase the friction causing a greater load on the actuating mechanism or may decrease the life of either the hinge or actuating mechanism.

Therefore an object of this invention is to produce a novel hinge construction that will not bind even though one of the hinge members is not correctly aligned.

Another object of this invention is to produce a novel hinge construction of pivotal type.

Another object of this invention is to provide a hinge construction having a floating action between the stationary and movable parts.

With these and other objects in view, the invention consists in the arrangement, construction and combination of the various parts of the approved device, as described in the specification, claimed in the claim and illustrated in the accompanying drawings, in which:

Figure 1 is a fragmentary elevation of a vehicle door showing the ventilator installation.

Figure 2 is a sectional elevation of the ventilator taken on line 22.

Figure 3 is an enlarged view of hinge construction.

In the production of automobile bodies the ventilators inserted in the door frames must be inherently flexible so that they may be brought into coincidence with the door frames. The ventilator subassembly forms with the door frame a unitary structure that is windand watertight. This is brought about by attaching a flexible ventilator frame having fastened thereto a resilient seal of rubber or the like to the door. The ventilator frame is therefore juxtaposited to the exact contour of the door frame. However, since the contour of all door frames is not dimensionally per-.-

2 feet and the ventilator frame is forced to coincide. the hinge structure must therefore bear the displacement caused by variances inthe doors.

As mentioned above, resent day hinges consist. of two stampings that are formed so that when comprises a mounting frame I2 and glass frame l3. Interposed between mounting frame l2 and glass frame I3 is a resilient seal I4 of rubber, or the like.

Seal I4 is fastened to mounting frame I2, has flap portion I5 completely concealing frame member I2. Seal I4 has also overlapping edges I6 contacting glass frame [3. A portion of the overlapping edge I6 is on one side of glass frame I3 and the other on the opposite side, the change occurring at the pivotal points, thereby allowing the axial pivot of glass frame I3 about the axis shown as the cutting line 22.

The glass frame [3 has rigidly attached thereto a lower hinge member I"! which is inserted thru mounting frame l2. The remainder of the hinge is composed of friction members I8, spacers I9, and spring 2!). Friction members I3 are secured to the mounting frame. The glass frame I3 is fixed except for axial movement by spring 2!! which also determines the amount of force required to pivot the frame.

The upper hinge 22 is a pivotal and slideable hinge and is made up of cylindrical cup 23 secured to glass frame and ball and shaft 24 which is secured to the mounting frame.

Referring to Figure 3, it is seen that considerable movement may be obtained in any direction and that the diameter of the shaft may be reduced to allow still greater movement. Thus within the limitation of the overlapping seals, mounting frame I2, a pressed steel stamping, may be deformed by compression, extension, or torsion to fit the door frame without imposing a force on the glass frame tending to change the axis.

It is possible to form a more resilient hinge of the type disclosed above by also providing the ball with a cap (not shown) of rubber or the like. In this manner the rubber cap or bushing wo ld allow movement of sumcient scope to cope with normal inaccuracy of parts and at the same time provide insulation against noise and prevent wear.

It is to be noticed that ventilators of the type disclosed have considerable spring loading on the lower hinge. It is readily seen, therefore, that the spring tensioning means will not yield whenever the mounting frame must be forced to fit a door frame.

Certain changes may be made in the construction disclosed without departing from the spirit of the invention and it is the intention to cover by the claim such variation as may be reasonably included therein.

The invention claimed is:

In a pivotal automobile window assembly comprising in combination a flexible mounting frame,v

a glass bearing frame, a resilient sealing strip attached to said flexible mounting frame, a lower and an upper oppositely spaced hinge member between said flexible mountingframe and said glassbearing frame whereby said glass bearing frame may be pivoted with respect to said flexible mounting frame, said lower hinge member fixed in a manner to prevent longitudinal movement between said flexible mounting frame and said glass bearing frame, said upper hinge mem- REFERENCES CITED The following references are of record in the file of this patent:
